The N balance was calculated as the difference between inputs (fertilizer, manure, wastewater treatment facility effluent, N fixation, and atmospheric deposition) and outputs (crop uptake and removal in harvest and gaseous emissions to the atmosphere). The P balance was calculated as the difference between inputs (fertilizer, manure, wastewater treatment facility effluent, and weathering) minus outputs (specifically, P harvested and removed in crops, hay, and pasture).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P97TCDQJ", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.6570f9fed34e952b2273f107.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6570f9fed34e952b2273f107", "keyword": ["National Water Quality Program", "USGS:6570f9fed34e952b2273f107", "Weighted Regressions on Time Season and Discharge (WRTDS)", "eutrophication", "inlandWaters", "legacy nutrients", "nitrogen", "phosphorus", "surface water quality", "water quality trends"], "modified": "2024-02-22T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-114.9146, 27.9804, -75.7819, 50.3731", "theme": ["geospatial"], "title": "Nutrient balances, river loads, and a counterfactual analysis to determine drivers of Mississippi River nitrogen and phosphorus loads from 1975 to 2017"}
